ITP in childhood: difficulties in the individual treatment.

To date, immunoglobulin preparations and corticosteroids are the most important therapeutic principles in idiopathic thrombocytopenic purpura (ITP). Initial treatment with high-dose immunoglobulins (HD-IgG) as well as the following prednisone therapy, however, were only of short lasting success in three children with newly diagnosed ITP. Recurrent bleeding tendency tempted to combine both drugs. A desired longterm elevation of platelet counts, however, was not achieved. Administration of Anti-Rho (D) to two of the patients was also disappointing. Splenectomy which could not be postponed any longer has already led to 17 and 21 months lasting remissions in 2 patients, respectively. The third patient who required monthly single doses of HD-IgG for 6 months after surgery, is in a partial remission since 27 months now. All types of drug administration--alone, consecutive or even combined--must be considered to defer splenectomy. As experienced in our patients, however, splenectomy still seems to be justified in case even such individually adapted therapeutic approaches fail.

Human platelet antigen gene frequencies in the Austrian population.

Gene frequencies for the human platelet antigen systems HPA-1, -2, -3, and -5 were determined directly from DNA isolated from cord blood of more than 900 randomly selected Caucasoid newborns in Vienna, Austria. Genotyping was performed by specific amplification of the respective regions coding for platelet glycoproteins GP Ib, IIb, IIIa, and Ia by PCR. These PCR products were analyzed after restriction enzyme digestion and electrophoresis. The observed gene frequencies were: HPA-1a: 0.852, HPA-1b: 0.148; HPA-2a: 0.918, HPA-2b: 0.082; HPA-3a: 0.612, HPA-3b: 0.388; HPA-5a: 0.892, HPA-5b: 0.108. There was a good fit with the Hardy-Weinberg equilibrium. Results from serological determinations and genotyping showed no discrepancies.
